How to activate ANOTHER object's actuator (Python)? Really!
from bge import logic

cont = logic.getCurrentController() #Camera
cube = logic.getCurrentScene().objects['Cube']
print(cube.controllers)
print(cube.actuators)
cube.controllers[0].activate(cube.actuators[0]) #AttributeError: 'SCA_ANDController' object has no attribute 'activate'
cont.activate(cube.actuators[0]) #ValueError: Motion not in this python controllers actuator list


The solution: Send a message to trigguer a message sensor to trigger the and controller to trigger the action actuator



In your script:

from bge import logic

cont = logic.getCurrentController()

cont.owner.sendMessage('anySubject')


or just:

from bge import logic

logic.sendMessage('anySubject')
